Looked into performance issues of GpgOL, turned out that other Addins were causing high amounts of decryption

Implemented "Preview" in GpgOL to show contents of a mail while verification (auto-key-retrieve, CRL checks etc.) happens.

This is esp. helpful for multipart/signed because it can show contents immediately.

Fixed printing in GpgOL when the selection of the printer changes.

Triaged some more GpgOL issues. Tried out "MailArchiver" plugin.

This week:
I feel well enough to work on more difficult tasks. -> OpenPGP & S/MIME combined in GpgOL.
As I estimate about 2d more work on the GpgOL side of things and ~1d on the Libkleo (cert resolution gui) I might get it done this week an and continue on to Smartcards. Depending on how much external stuff comes in.

Realized that when importing secret key from gpg to gpg-agent, encrypted part is decrypted by gpg-agent, and the structure is defined by OpenPGP using GCRY_FMT_PGP. This part is not decoupled well between gpg and gpg-agent.
